Assessing the Holocene paleoenvironmental history of Lake Scugog

Assessing the Holocene paleoenvironmental history of Lake Scugog

by Randelle Adano Lake Scugog is a large, shallow reservoir in southern Ontario that has faced multiple stressors like climate change, eutrophication, and invasive species over the post-industrial period. The arrival of the first, early settlers in ~1700 has brought significant infrastructure development in the area, most notably the building of the Lindsay Dam in

Knowledge co-production to address human-polar bear conflict in Southern Hudson Bay and James Bay

Knowledge co-production to address human-polar bear conflict in Southern Hudson Bay and James Bay

Polar bears in Ontario are at the southern limit of their species’ range. As part of the Southern Hudson Bay subpopulation, these roughly 800 bears migrate onto land when the sea ice of Hudson Bay melts completely each summer. On shore, polar bears primarily fast and rely on stored fat for energy. With increasing global

Climate change and differing lake characteristic's impact on cyanobacteria bloom formation in oligotrophic systems

Climate change and differing lake characteristic's impact on cyanobacteria bloom formation in oligotrophic systems

Cyanobacteria, commonly referred to as Blue-Green Algae, are a ubiquitous photosynthetic bacteria that under the right conditions – high light, warm temperatures, high nutrient concentrations, high thermal stability, low surficial sediment redox– cyanobacteria are able to rapidly proliferate, forming dense populations or blooms (often creating dense mats on the water surface). Freshwater blooms are detrimental

Drivers and consequences of individual specialization in an Arctic marine top predator

Drivers and consequences of individual specialization in an Arctic marine top predator

Principal Investigator: Gregory Thiemann Funding: NSERC Discovery Grant. Term: 2021-2026. The proposed research involves testing hypotheses around the environmental drivers and ecological consequences of individual specialization, using the polar bear (Ursus maritimus) as a model species and target for conservation. As a long­-lived top predator in a dynamic habitat, polar bears demonstrate several characteristics that

Characterizing the denning habitat and movements of polar bears in Southern Hudson Bay

Characterizing the denning habitat and movements of polar bears in Southern Hudson Bay

The research aims to inform and advance Government Response Statement (GRS) actions, as well as provide new insights into the ecology of polar bears in Ontario. The overarching goal is to better understand the influence of climate change on the ecology and biology of polar bears in Southern Hudson Bay. Funding:  Species at Risk Research

Ocean frontiers: An interdisciplinary workshop on the changing contours of marine space and resource access

Ocean frontiers: An interdisciplinary workshop on the changing contours of marine space and resource access

This two-day workshop, entitled “Ocean Frontiers: An Interdisciplinary Workshop on the Changing Contours of Marine Space and Resource Access,” brought together a network of interdisciplinary scholars to explore the political-economic and ecological dynamics that shape new resource practices in marine zones. The overall goal was to unite social scientists and ecologists to share their understanding

Canadian Polar Bear Body Condition

Canadian Polar Bear Body Condition

Environment Canada (EC) The project monitored trends in the nutritional condition of polar bears in the Canadian Arctic and examined the relationships between body condition and ongoing environmental change. Researcher: PI: Greg Thiemann Project Theme: Resource Management

Using Phosphorus-Ferrous Eutrophication Model to Identify Cyanobacteria Bloom Formation Risk in Georgian Bay Embayments

Using Phosphorus-Ferrous Eutrophication Model to Identify Cyanobacteria Bloom Formation Risk in Georgian Bay Embayments

Georgian Bay Forever The project aimed to provide Georgian Bay Forever and government agencies with a sounder scientific understanding of risk factors of cyanobacteria blooms in the embayments of Eastern Giorgian Bay, especially those factors that influenced oxygen depletion of surface sediments. Researcher: Co-PIs: Lewis Molot, Sue Watson (Environment Canada's National Water Research Institute )
